Description

一种隔热布料及其制备方法
技术领域
本发明属于布料加工技术领域，特别涉及一种隔热布料及其制备方法。
背景技术
布料是装饰材料或者制备某些产品的常用材料，包括隔热衣服、地毯、窗帘、遮阳伞、遮阳布等，如今还有很多人采用布料对墙面进行装饰用或隔热用。随着人类对健康生活和工作要求的提高，越来越多的家用及工业用隔热布料产品增加，隔热布料的应用也越来越广泛。隔热布料为一种功能型布料，在使用布料的同时赋予其它功能，使其同时具有布料的柔软，又能具有隔热效果。
中国专利CN 107263951 A公开了一种隔热布料及其制备方法，该种隔热布料包括隔热层、第一保温层及第二保温层，隔热层顶部涂有纳米涂层包裹的防水层，所述隔热层采用金属线、麻线、绵羊毛线及棉线相互编织而成，所述金属线包括第一金属缝纫线和第二金属缝纫线，所述第一金属缝纫线和第二金属缝纫线的外表面采用隔热粉材料，以此实现隔热功能。然而由金属线制成的布料其柔韧性不好，而且金属价格较为昂贵，金属线表面涂覆的隔热粉会粘附不牢而逐渐掉落，使其逐渐失去隔热功能，其制备方法较为复杂。
发明内容
发明目的：为了克服以上不足，本发明的目的是提供一种隔热效果好的布料，该种隔热布料具有较好的隔热效果，适用于制造挡光布、遮阳伞、遮阳布等需要抵挡太阳光进行隔热的产品，该种隔热布料的制备方法简单，原料来源充足，适用于工业大规模应用。
技术方案：一种隔热布料，从上至下依次包括反光层、防辐射层、隔热层及基布层。反光层可反射部分太阳光，防辐射层可阻止太阳光中的紫外线透入，隔热层起到阻隔太阳光热量的作用。
进一步的，所述反光层为涂有反光涂料层。反光涂料使布料具有反射光的作用。
进一步的，所述反光涂料由如下重量配方的混合物组成：反光粉5-10份、丙烯酸树脂20-40份、水性环氧树脂1-5份、二甲基硅油1-5份、羟乙基纤维素钠1-5份及无水酒精30-70份。反光粉在各种复杂形状的表面上都可以使用，具有很强的光反射率。
进一步的，所述防辐射层为纳米银及纳米二氧化钛的复合层，所述复合层中纳米银与纳米二氧化钛的重量比为2:1。纳米银具有防辐射、防静电、强抗菌及对人体安全等优点，而纳米二氧化钛对紫外线的屏蔽作用强，具有较好的抗辐射性能。
进一步的，所述纳米银粒径大小为10-25nm，纳米二氧化钛粒径大小为50-100nm。纳米银颗粒小粒径具有较好的抗菌效果，而纳米二氧化钛在其粒径较小时，其活性较大，既能反射、散射紫外线，又能吸收紫外线，从而对紫外线具有更强的阻隔能力，具有更好的抗辐射效果。
进一步的，所述隔热层为包含纳米中空玻璃微珠层，所述纳米中空玻璃微珠的粒径大小为100-250nm。中空玻璃微珠具有重量轻、体积大，导热系数低，分散性好，流动性好，化学稳定性高等特点，而且来源充足，价格便宜，可以反射光线，作为隔热填充物可起到很好的隔热效果。
进一步的，所述基布层包括涤纶15份、人造纤维35份及棉纤维40份。涤纶即聚酯纤维，具有较好的抗皱性和保形性，具有较高的强度和弹性恢复能力；人造纤维来源充足，价格便宜，性能优异；棉纤维制成的织物坚牢耐磨。
一种隔热布料的制备方法，包括以下步骤：
(1)将丙烯酸树脂20-40份、水性环氧树脂1-5份、二甲基硅油1-5份、羟乙基纤维素钠1-5份及无水酒精30-70份置于搅拌器中混合，搅拌均匀后再逐渐加入反光粉5-10份，于40-50℃温度下搅拌0.5-1h，所得均匀混合液即为反光涂料；
(2)将涤纶15份、人造纤维35份及棉纤维40份经纺织机进行纺织，即可制得基布层；
(3)将步骤(2)所得的基布层表面均匀涂上步骤(1)所得反光涂料，反复涂刷三遍，然后于50℃烘箱中烘24h，即可制得反光层；
(4)使用热熔胶将重量比为2:1的纳米银及纳米二氧化钛复合物均匀覆盖于步骤(2)所得的基布层表面，即可制得防辐射层；
(5)使用热熔胶将纳米中空玻璃微珠均匀覆盖于步骤(2)所得的基布层表面，即可制得隔热层；
(6)将所制得的反光层、防辐射层、隔热层及基布层按从上至下的顺序各层之间采用压膜复合或热熔粘合方式复合得到布料。
进一步的，所述步骤(4)中纳米银及纳米二氧化钛复合物的覆盖厚度为100-350nm。覆盖厚度太厚则影响产品的柔韧性，覆盖厚度太薄则使其防辐射效果不好。
进一步的，所述步骤(5)中中空玻璃微珠的覆盖厚度为200-400nm。覆盖厚度太厚则影响产品的柔韧性，覆盖厚度太薄则使其隔热效果不好。
上述技术方案可以看出，本发明具有如下有益效果：本发明所述的一种隔热布料表层设有反光层，反光层的反光涂料使其可反射掉一部分太阳光；反光层下设有防辐射层，可阻止紫外线的透入；防辐射层下设有中空玻璃填充的隔热层，可进一步反射掉部分太阳光，而且还能减少太阳热量的透入，使其具有较好的隔热效果。该种隔热布料具有较好的隔热效果，适用于制造挡光布、遮阳伞、遮阳布等需要抵挡太阳光进行隔热的产品，该种隔热布料的制备方法简单，原料来源充足，适用于工业大规模应用。
